Dear Mr. Smead: This is in response to your letter of February 6, 1976, concerning th application of 49 CFR Part 574, *Tire Identification and Recordkeeping*, to certain off-road motorcycle tires that you plan to import.; 'Motor vehicle' is defined in Section 102(3) of the National Traffi and Motor Vehicle Safety Act of 1966 as:; >>>any vehicle driven or drawn by mechanical power manufacture primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.<<<; The Tire Identification and Recordkeeping regulation does not apply t tires that are not manufactured for use on motor vehicles. From the description in your letter, it appears that the vehicles for which the tires in question are designed are not motor vehicles. Therefore, unless these tires are also designed for use on other vehicles that do meet the statutory definition of 'motor vehicle', they are not subject to any labeling requirements of the Department of Transportation.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
